A mindless task for a lazy weekend: convert all the README and README.txt files to Markdown. Paired with the slow conversion of all of our man pages to Markdown, this gives a uniform language to the Open MPI docs. This commit moved a bunch of copyright headers out of the top-level README.txt file, so I updated the relevant copyright header years in the top-level LICENSE file to match what was removed from README.txt. Additionally, this commit did (very) little to update the actual content of the README files. A very small number of updates were made for topics that I found blatently obvious while Markdown-izing the content, but in general, I did not update content during this commit. For example, there's still quite a bit of text about ORTE that was not meaningfully updated. Signed-off-by: Jeff Squyres <jsquyres@cisco.com> Co-authored-by: Josh Hursey <jhursey@us.ibm.com>
